Abstract

The invention provides preparation and application of efficient photoprotection spirulina-based high internal phase gel emulsion. Spirulina protein is prepared into spirulina protein nanoparticles by using an anti-solvent method, and the prepared spirulina-based high internal phase emulsion uses all-natural bio-based particles; meanwhile, the prepared spirulina-based high internal phase emulsion can be used for loading beta-carotene sensitive to light, and the higher the concentration of the spirulina protein nanoparticles in the high internal phase emulsion is, the better the photoprotection effect is. Preferably, the concentration of spirulina protein in a spirulina protein solution is 32 mg / mL, the volume ratio of absolute ethyl alcohol to the spirulina protein solution is 3: 1, spirulina protein nano-particles are dispersed in deionized water to enable the concentration to be 0.5-9% (w / v), 3-5.67 volume of isohexadecane is added, the pH is controlled to be 1.5-9.5, all the process conditions act together, and the spirulina protein nano-particles are prepared. The prepared spirulina-based high internal phase emulsion has excellent storage stability and photoprotection property, and is a potential delivery system for photosensitive bioactive substances.

Description

technical field [0001] The invention belongs to the technical field of cosmetic processing and application, in particular to the preparation and application of a high-efficiency photoprotective spirulina-based high internal phase gel emulsion. Background technique [0002] The emulsion stabilized by colloidal particles is called Pickering emulsion, which has many advantages such as high stability, good biocompatibility, less foaming during emulsification and no pollution to the environment. Currently, various inorganic particles (eg, silica, clay minerals, titanium dioxide) and biological particles (eg, cellulose, chitosan, lignin, starch, lipid nanoparticles, and protein nanoparticles) are used to stabilize emulsions. Bioparticles have high biocompatibility and biodegradability, making them more attractive for food-grade and cosmetic-grade emulsions. [0003] The methods of preparing proteins into nanoparticle stabilizers mainly include enzymatic cross-linking method, ther...
